MEANS FOR FASTEINING HYDRANT-TOPS, 86C.

SPECIFICATION forming part of Letters Patent No. 268,686, dated December 5, 1882.

Application filed April 6, 18852. (No model.) i

To all whom it may concern:

Be it known that I, WILLIAM KAISER, a citizen of the United States of America, residing at NVilkes-Barr, in tle county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Means for Fastening Hydrant Tops, Sto.; and I doA hereby declare the following to be a full, clear, and exact description of the invention, such 1o` as will enable others skilled in the art to which zo is a vertical section, showing the hood and stock connected. Fig. 2 is a side view of the hood separately. Fig. 3 is a side view of the stock separately. Fig. et is a cross-section of the parts on the line m a: in Fig. 1.

'lhe letter A designates the hood 5 A', the top or cap to the hood. The hood is cylindrical and made of cast-iron.

B represents the stockof a hydrant or pump, and consists of a tube whose upper end ts within the lower end of the hood. The hood stands in a vertical position, and upon the inner side of the wall and near the lower end the hood has a groove, o, which extends for a short distance in a horizontal direction around the curved face of the wall. The shape of this groove in cross-section is half-round,as seen in Fig. l. A hole, c', in the hood passes through the wall thereof in a direction tangential to the outer side of the c) linder, and leads into the inside groove, c. On the side of the hood diametrically opposite the inside groove, c, a

set-screw, d, entersand .passes through the` A piece the hole c in the hood. This, as hereinafter explained, serves as a key. The two parts are united by the lower end of the hood. setting v down `over the end ot the tube which has the annular groove on its exterior. The segmentshaped key Fis then inserted endwise into the hole c inthe hood. This key will thereby take position partly in the groove e on the stock and partlyin the groove c on the inside of the hood, as shown in Figs. l and 4. The setscrew d on the opposite side should then be turned until its end enters the annular groove e. When the set-screw is tightened it has the effect to draw the opposite side of the hood close against the stock, or close against the key F. The latter` then by its position, partly in each `of the grooves on the two parts, serves to secure 'the hood from removal. When it is so desired the removal of the hood or top is easily effected by simply turning the set-screw d, by which its end is withdrawn from the annular groove c. The key F may then he drawn out and the two parts separated. The setscrew d serves as a tightening device, as already explained; but any other device which will produce the same effect may be used instead of the setfscrew.

The hole c' to enter the key may be dispensed with by forming on one ofthe parts a socket large enough to afford reception for the key, in order that the said key may be placed there- .in previous to the parts being put together.

By the socket being in connection with the grooves c and e, and the key being loosely in the socket, the key may, after the parts are put together, be directed into its position between the two groovesby the jarring motion imparted to the parts by the tap of a hammer. While this means offasteningis shown applied to a hydrant, it is applicable to other devices, such as pumps and other things where two parts are to be similarly connected. Furthermore, it is immaterial whether the lower end of one part sets down over the upper end of the other part, or whether the relative positions are reversed-that is, the lower end of one part setting down inside of the upper end of the other part.

In the drawings, an inward shoulder, g, is shown extending around the inner side of the IOO Wall of the hood, and a metal Washer, h, is also shown between the said shoulder and the up` per end of the stock. These features are useful in the case ot' a hydrant or similar device, but are not essential to the operation of the fastening means herein claimed.

The opening' z' in the Wall of the hood is for lthe nozzle of the hydrant to project through.

Having described my invention, I claim and desire to secure by Letters Patent of the United States- In a hydrant, the herein-described means of securing the top and stock together, consisting WILLIAM KAISE R.
